Original No. 1,747,760, dated February 18, 1930, Serial No. 220,394, filed September 19, 1927. Application '!or reissue filed August 1, 1931.

The present invention relates to a bottle cap and stopper for use on bottles deslgned for receiving the,usual crimped cap, the

present combined stopper and cap being used.

' as to furnish a tight seal for bottles having 0 after a charged content. To the accomplishment of the foregoing and related ends, said nvention, then, consists of the means here1nfully described and particularly pointed out in the claims.

The annexed drawing and the followlng description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing:

Fig. 1 is a vertical sectional view showing a combined cap and stopper n place m a bottle neck; Fig. 2 is a view similar to Fig. 1, but showing a slightly modified structure;

Figs. 3 and 1 are sectional-views of the caps and stoppers shown in the bottle necks 1n Figs. land 2 respectively; Figs. 5 and 6 are sectional views of modified forms of the stoppers shown in Figs. 3 and 4 respectively.

In Figs. 1 and 2 the usual type of bottle neck is shown, this neck 1 having an outwardly bulging portion 2 with an outer portion 3 of reduced diameter. and terminating at the top in a slightly overhanging flange or rim 4. The interior of the neck has an enlarged portion 5' corresponding with the bulge -2 on the outside.

The present combined cap and cork as shown in Figs- 1 and 3, provides a stopper portion 10 slightly tapered in general shape but having an enlarged ring or flange 11 adjacent the bottom, the length of the stopper Serial No. 554,559.

portion being'sufficient to allow the flange 11 to seat itself in the enlarged portion 5 of the bottle neck when the cork is forced into the bottle. In the form shown in Figs. 1 and 3 the bottom of the stopper is concaved as at 12 and thus when in place in the bottle, the internal gas pressure tends to expand the sides of the stopper including the ring 11 into the enlarged bottle neck 5, thus aiding the seal. In the form shown in Fig. 5, the end of the stopper is convex rather than concave. In both cases the ring portion 11 of the stopper tapers slightly as does the upper portion 14 as this aids in forcing the stopper into position.

The upper portion of the combined unit comprises a disc-shaped top 15 formed integrally with the stopper 10, and this disc portion has a downwardly extending outwardly flaring flange 16 which terminates in an inwardly extending ring portion 17 formed with an upwardly beveled lower edge 18. This flange 16 is sufliciently long to al low thering 17 to engage under the upper bulge 2 hf the bottle neck where it engages snugly much in the same manner as the usual crimped cap except that the present stopperis made of a resilient material such as rubgage in the enlarged portion 5 of the bottle neck, with an encircling head or rin 21. The bottom 22 of the stopper may be elther convex as shown in Figs. 2 and 4, ormay be hollowed out as at 23, shown in Fig. 6.

The .inwardly beveled edge 18 on the cap portion of the stopper allows the cap to cam itself into engaging position over the bottle neck and at the same time aids in easy removal as it forms a finger grip so that one side ma be moved up and over the top bulge of the ottle when'the further removal is easil accomplished.

It as been found that with the extra flange or ring on the stopper portion adapted to seat tightly in the interior enlargement of' the bottle neck that the (present combined cap and stopper will 1101 under relative high gas pressure in the bottle and will prevent any leakage. The .umt must of course be made of resilient material, a good grade of vulcanized rubber producing the most satisfactor results. These units may be used reeate ly, and until their resiliency is lost, will effectively seal the usual type of bottle I holding charged beverages such as ginger ale, I near beer,-and the like, without the loss of either liquid or gas. H

Other modes of applying the principle of our invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the meansstated by any of the follow ing claims or the equivalent of such stated means be employed.

We therefore particularly point out and distinctly claim as our invention:

1. A combined rubber bottle cap and stopper consisting of a stopper portion in the form of an elongated slightly tapering plug,

. said plug having an enlarged ring adjacent the lower end, said plug having a concave bottom surface of a depth not exceeding that of said enlarged ring and an integrally formed cap member having an outwardly and downwardly depending flange terminating in an inwardly extending thickened ring portion, said flange and ring portion being adapted to be forced over and around the bottle neck to bring said ring portion into elastic. engagement therewitlrbelow the upper head.

2. A combined rubber bottle cap and stopper consisting of a stopper portion in the form of an elongated slightly tapering plug, said plug having an enlarged ringadjacent the lower end, said ring being also slightly tapered and being sopositioned, as to normally engage in the enlarged portion of a bottle neck, said plug having a concave bottom surface of a depth not exceeding that form of an elongated slightly tapering plug,

said plug having an enlarged ring adjacent the lower end, said ring being also slightly tapered and being so positioned as to normally engage in the enlarged portion of a.

bottle neck, said plug having a concave bottom surface of a depth not exceeding that of said enlarged ring, and an integrally formed cap member having an outwardly and downwardly depending flange terminatin in an inwardly extending ring portion, said flange and ring portion being adapted to be forced over and around the bottle neck to bring said ring portion into elastic engagement therewith below the upper head, the lower edge of said flange and ring portion being tapered upwardly and inwardly to facilitate both mounting and removal "of said combined cap and stopper.

4. A closure means for bottles and the like comprising a cap portion and a stopper por tion formed integrally therewith, said stopin its lower end, and said cap portion having an outwardly and downwardly depending flange terminating short of the lower end of said plug and adapted to be forced over and around the bottle neck to bring the lower end of said flange into elastic engagement therewith below the rim thereof.

5. A closure means for bottles and the like comprising a cap portion and a stopper portion formed integrally therewith, said sto'pper portion being in the form of an elongated slightly tapering plug having a recess in its lower end and an enlarged ring of substantially semi-circular cross section adjacent said end, and said cap portion having an outwardly and downwardly depending flange terminating shortof the lowerend of said plug and adapted to be forced over and around the bottle neck to bring the lower end of said flange into elastic engagement therewith below the rim thereof.

6. A closure means for bottles and the like comprising a cap portion and a stopper portion formed integrally therewith, said stopper portion being in the form of an elongated sli htly tapering plug having a recess in its lower end, and said cap portion having an outwardly and downwardly depending flange terminating short of the lower end of said plug in an inwardly extending thickened ring portion, said flange and ring portion being adapted to be forced over and around the bottle neck to bring said ring portion into elastic engagement there with below the rim.
